. There has recently come into use a high speed twenty-two calibercartridge having a speed of twenty-five hundred feet per mlnute and ablank range of approximately two hundred yards In order to avoidthe-necessity of designing a new rifle to handle these cartridges I havedevised novel means whereby the higher caliber rifle movements can beadapted to utilize these high speed cartridges, the barrel beingreplaced by one which is adapted to receive a twenty-two calibercartridge. With the above and other objects in vlew, as will hereinafterappear, my invention comprehends novel loading mechanism for rifles. i

It further comprehends novel rifle loading mechanism wherein the bolt isprovidedwith a novel constructionand arrangement of a cartridge pick-up.

It further comprehends a novel magazlne and novel means for securing itto the floor Other novel features of construction and advantage willhereinafter more clearly appear in the detailed description and theappended claims. y For the purpose of illustrating the nvention, I haveshown in the accompany ng drawing a typical embodiment of 1t, winch, inpractice, will give satisfactory and reliable results. It is, however,to be understood that the various instrumentalities of which myinvention consists can be variously arranged and organized, and myinvention is. not lim- 7 ited to the exact arrangement and organizationof these instrumentalities as herein set forth.

Similar numerals of reference indicate corresponding parts. i i 1Referringto the drawing: p

l designates the breech of a light weight rifle embodying my invention.2 designates the barrel having a bore to receive a .22 cartridge. 3designates the bolt which is constructed and operates in theconventional manner except for my novel-cartridge pickup 4. The bolt isslotted as at 5 to receive the cartridge pick-up, and the rear end ofsuch slot terminates .in a rounded recess 6 adapted to; receive therounded head 7 connected with the body portion of the cartridge pick-upbya neck 8. The extractor ring 33 which is seated in an annular grooveinthe bolt extends over the heads-7 so that the car tridge pick-up is,pivotally, supported at its rear end. A spring 9 between the bolt andthe cartridge pick-uptends ,to move the forward end of the latteroutwardly. The bolt and cartridge pick-up are recessed to receive andposition the free ends of the spring.

The conventional magazine is of such size that-it cannot be used with a.22 cartridge. It therefore becomes necessary to redesign it for thispurpose. The magazine consists of a casing 10 preferably rectangular incontour and; provided with a rearwardly extending base flange 11 whichextends beneath a spring metal clip 12 having one end secured to thefloor plate 13 by means of a fastening devicel nl The magazine-haswithin it a spring 15 having a zig zag contour,-and the forwardlyextending lower portion is adapted to pass beneath the inwardly directedflanges 16 of :the floorplate. The spring 15 at its upper end terminatesin a forwardly extending portion which abuts against thedownwardly-directed forward'flange 16 of thecartridge follower 17 whichhas a similar flange 183131118 rear end. Opposite side walls ofthe'magazine are inwardly deflected at their upper ends as at 19 tooverhang the cartridge follower and limit its upward movement. 20designates a stop and magazine cover in the form of a bent spring, thelower end of which is secured to the Usage.-

7 upper end as at 23. The forward upper en of the magazine is cut out asat 24. The cartridge follower has a raised rib 25. The breech has therounded shoulder-'26 which directs a cartridge when fed forwardly-byth ees-r tridge pick-up to the bore of the barrel. 27

are the conventional locking lugs on the bolt: and 28 is the bolthandle.

29 is the conventional entractor carried by the bolt. 30designates thecartridge. p

The operation will now be apparent to those skilled in this art andis asfollb'ws,

Assuming that the cartridges are in the ma a'zine, the bolt handle 28"is raised and the jolt 3'retrac ted. The bolt moved forwardly. The rim of the cartridge is resting against the stop' 22 and as the bolt advancesthe upper end of'the spring 20 is pressed downwardly theca'rtridge pickup 4 'sothatthe forward end-of the latter sonnets with the rim ofacartridge and moves thelatter forwardl with it. The forward end of thecartri ge "rides up .on

' the shoulder 26, see Figure 2, and is directed into the bore of thebarrel, The bolt handle 28 is now swung downwardly and the bolt islocked imposition with the pin 31 'i'eady to be released b the trigger32.

It Will be noted that t e magazine housing 34 has'con'nected to it thefloor plate and thus "forms an outer magazine within is detachablymounted art cartridge maga- Zinc 10. p I It willno'w "be apparent that Ihave devised "a new and use-n11 rifle loading mecha nism which embodiesthe' features of advantage enumerated as'desirable' in the statemnt'o'fthe invention and theabove description, and while I have, in the presentinstance, shown and described a preferred em bodiinent thereofwhicihiWill give practicesatisfactory and reliable results, it is tounderstood'that this embodiment is susceptible of modification in"various particulars without departing from the spirit or scope of theinvention orsa'crificingany of its advantages.

Having thus describedmy invention what I clalm as new and desire tosecure by Letters Patent, is
